Hi Folks,
I saw on https://gmauthority.com/blog/2023/10/next-generation-chevy-bolt-ev-to-use-lf p-battery-cells/ that GM is moving to (what hobbiests like me used in conversions LiFePO4 in early 00's) but are currently using NCMA (Nickel Cobalt Magnesium Aluminum from LG-Chem?) I though all current EV's were NMC Nickel Manganese Cobalt cathode with a lithium substrate-dielectric and carbon anode per www.batteryuniversity.com <http://www.batteryuniversity.com> . After Shelor Chevy finally replaced my battery last week (after a month of nagging & faulted new software indicating bad cells), I noticed the new label (installers were clueless on chemistry) showed: LiMM-C.F, B2.0.1, 64kWh, 24052284, serial: 4823254RES006287. I couldn't find *any* translation for LiMM-C.F. chemistry, does anyone know what that is? I assume it's still the LMC chemictry since I looked under a friend's 2023 purchased Bolt and saw the same label with yellow-blue-green assembly verification paint dots. Even with the new battery GM is *still* not requesting users to only charge to 80% for local trips like *all* other EV manufacturers do. Maybe they don't *care* about battery longevity? Battery University does say that LiFePO4 batts have less sensitivity to 100% charging, maybe they figure that changing to that will help with clueless EV (charge level) drivers.
